Weight, size, departure point and destination are needed before you could get a yes or no or by how much.
For $14 I can ship 4.5 kg from Ottawa to all the US North East states (as far sount as DC) westward to Ohio.
OR 3.5 kg to include all the way south to Florida and west to Mississippi and the Dakotas.
OR 2.5 kg all the way to Hawaii and Alaska.
Thats with a commercial account and manual manifests.
